This is the one I bought.

I had one from Cabela's but I kept getting it wet when I'd walk pivots without a rainsuit.
I had the moneyclip type and it digs into my leg when I'm in the tractor and it's pressed up against my leg and then motion of the seat just digs right into my leg for 18 hours a day. That's why I went back with leather.
That carbon fiber one penguinz posted looks pretty good, in the event I quit becoming a cheap ass.
But that's unlikely. Fact is dirt and occasional water is hard on wallets, so I have trouble dropping coin on them.
